I have a number of problems based on "beginner math examples for combinations" I have tried a lot to solve them myself but in vain. Our teacher has asked us to figure them out ourselves and then explain them to the entire class. I reckon that I will be chosen to do so. Please help me!

What exactly don't you understand about "beginner math examples for combinations"? I remember having difficulty with the same thing in College Algebra, so I might be able to give you some suggestions on how to handle such problems. However if you want help with algebra on a long term basis, then you should try out Algebrator, that's what I did in my Algebra 2, and I have to say it's the best ! It's less costly than a private teacher and you can count on it anytime you want . It's very easy to use it , even if you never ever tried a similar program. I would advise you to get it as soon as you can and forget about getting a math teacher. You won't regret it!
